I think it was less "too fast" and more that 10gbase-t is crazy power hungry and significantly reduced run length. End result is basically 0 adoption in the enterprise so there was little to no trickle down to the consumer market. The power draw also made it extremely difficult to make a 10gbt dongle for laptops and extremely expensive to put on a desktop motherboard.
